Download for Windows-7 64-bit

On Windows-7 64-bit systems, the simplest way to install Ra is to run the Windows
Ra 1.3.1 Win installer
(26 Aug 2011, based on R 2.13.1, about 3 MBytes).
It's easy and you get the benefit of a faster version of R.
You need to first have R 2.13.1 installed (64-bit build).
You should uninstall your old version of Ra, if any, before installing a new version.

Note: this installer has currently been tested only on 64-bit Windows-7 systems.
It has not been tested on other versions of Windows.

This README file tells you what the installer does.
The case study will give you an idea of what Ra can and can't do.
